Accout for the following : (ii) Melting point of an acid with even number is higher than those of its neighbours with odd number of carbons atoms.

Explanation

To account for the observation that the melting point of a carboxylic acid with an even number of carbon atoms is higher than those of its neighboring acids with odd numbers of carbon atoms, we can follow these steps:

### Step 1: Understanding the Structure of Carboxylic Acids
Carboxylic acids have the general formula RCOOH, where R is a hydrocarbon chain. The melting point of these acids can be influenced by their molecular structure, particularly the number of carbon atoms in the chain.

### Step 2: Identifying Even and Odd Carbon Acids
Consider two neighboring carboxylic acids:
- An acid with an even number of carbon atoms (e.g., butanoic acid, C4H8O2).
